Thirty-three 10-year-old boys repeatedly performed six symptom-limited, spiroergometric exercise tests according to the vita maxima method over an observation period of 4 years. Submaximum and maximum performance parameters were assessed and their correlation was calculated. The correlation of the heart rate at 1, 2 and 3 watts/kg body weight with the values of maximum performance capacity (wattmax and VO2max) and with the body-weight-related, relative maximum values was statistically significant. The correlation factors for the relative values were about twice as high (r = 0.55) as the absolute values (r = 0.27). The heart rate at 1, 2 and 3 watts/kg therefore was more characteristic of the relative values, which represent the state of training, and less for the absolute performance capacity, which depends to a great extent on body weight. However, the statistically significant correlation factors were too low to estimate reliably the state of training in an individual case. The correlation of physical working capacity at an HR of 170/min (PWC 170) with the maximum ergometric Watt performance was r = 0.80 and therefore appears to be sufficient to estimate the maximum performance capacity in children. This is however only valid for children over the age of 11.
33名10岁男孩在4年的观察期内，按照最大摄氧量法反复进行了6次症状限制的运动心肺功能测试。评估了次最大和最大运动表现参数，并计算了它们之间的相关性。1、2和3瓦/千克体重时的心率与最大运动能力值（最大功率和最大摄氧量）以及与体重相关的相对最大值之间的相关性具有统计学意义。相对值的相关系数（r = 0.55）约为绝对值（r = 0.27）的两倍。因此，1、2和3瓦/千克体重时的心率对于代表训练状态的相对值更具特征性，而对于在很大程度上取决于体重的绝对运动能力则特征性较小。然而，具有统计学意义的相关系数过低，无法在个体情况下可靠地估计训练状态。心率为170次/分钟时的体力工作能力（PWC 170）与最大运动功率之间的相关性为r = 0.80，因此似乎足以估计儿童的最大运动能力。然而，这仅适用于11岁以上的儿童。
